A friend of mine has just sent me these details:

Guys,

If Mars gets as big as the Moon, it'll be a real, once in a liftime treat!

->

>

> The Red Planet is about to be spectacular! This month and next, Earth is

> catching up with Mars in an encounter that will culminate in the closest

> approach between the two planets in recorded history. The next time Mars may

> come this close is in 2287. Due to the way Jupiter's gravity tugs on Mars and

> perturbs its orbit, astronomers can only be certain that Mars has not come this

> close to Earth in the Last 5,000 years, but it may be as long as 60,000 years

> before it happens again.

>

> The encounter will culminate on August 27th when Mars comes to within 34,649,589

> miles of Earth and will be (next to the moon) the brightest object in the night

> sky. It will attain a magnitude of -2.9 and will appear 25.11 arc seconds wide.

> At a modest 75-power magnification

>

> Mars will look as large as the full moon to the naked eye. Mars will be easy to

> spot. At the beginning of August it will rise in the east at 10p.m. and

> reach its azimuth at about 3 a.m.

>

> By the end of August when the two planets are closest, Mars will rise at

> nightfall and reach its highest point in the sky at 12:30a.m. That's pretty

> convenient to see something that no human being has seen in recorded history.

> So, mark your calendar at the beginning of August to see Mars grow progressively

> brighter and brighter throughout the month.

>

>

>

> Share this with your children and grandchildren. NO ONE ALIVE TODAY WILL EVER

> SEE THIS AGAIN

It's a nice idea but no. It'll look like it always does but brighter than usual. Still a dot to the naked eye. Still reddish.

Ah... I just worked out what you did wrong, John. It should be one sentence - "At a modest 75-power magnification, Mars will look as large as the full moon to the naked eye."

My binoculars are a modest 8x magnification. What on earth do you have that will achieve 75 times?

The Lovell telescope at Jodrell Bank should do the trick! ;)
